Archer TL-MR6400 Router: External Antenna for Improved Signal & Performance in Szklarska Poręba?

Hello,
I have a Router Archer TL-MR6400 router and with it Plus LTE internet in Szklarska Poręba. I use it mainly to view from the camera what works, but the Internet almost does not go at all, or loads pages very slowly.
Can you advise me if mounting an external antenna will improve the signal? There are 2 antennas in the router, but changing the position or location of the router does not help.
If I had to buy the antenna (s), which is the best? I don't care about the speed being stunning. Just as it begins to load pages and mail as normal. Youtube, radio or other streams are not a priority.

For testing, disconnect a colleague from the router camera and then check the network speed.

And what street in Szklarska Poręba do you use LTE1800aero2 or LTE800Sferii, what signal parameters and DL / UL results in speed test?

Even before connecting the camera there was a problem loading pages. I don't know which LTE I use (I will be there at the end of October and it will be difficult for me to provide this information)

Is it not enough to connect an antenna such as the one in the link?

Buy and find out. you made a mistake once when you bought the MR-6400. the router cannot select the LTE band. The nearest BTS Plus at the Bornit Hotel (Mickiewicza 21) is LTE1800Aero2 and LTE800Sferii. it's hard to say which one you're connecting to. On LTE1800 aero2 has 20MHz bandwidth in MIMO2x2 and DL up to 150Mbps, LTE800Sferii is only 5MHz in MIMO2x2 and DL up to 37.5Mbps. LTE800 range greater. Plus BTs in many locations are massively overloaded with low speeds.

Hello,
Buying the ATK-LOG ALP LTE MIMO 2x2 antenna 5m cable 800-3000MHz SMA plug solved the problem. I did not check the speed, but the page loads as it should and it was enough for this assessment. Previously there was a problem loading the page correctly.

Thanks for the information about where the transmitter is located. I directed the antenna towards him.

I close the topic.
